[Discuss-gnuradio] ABI compatibility error for installing Gnuradio and UHD respectively

[Alex Zhang]

Hi List,

I install the gnuradio and UHD in different time, and when I run a python script, it tells me:

RuntimeError: 
GR-UHD detected ABI compatibility mismatch with UHD library.
GR-UHD was build against ABI: 3.4.0-1,
but UHD library reports ABI: 3.4.0-2
Suggestion: install an ABI compatible version of UHD,
or rebuild GR-UHD component against this ABI version

I don't want to change the gnuradio, but want to rollback the UHD driver to ABI with 3.4.0-1.
I have tried the git checkout release_003_004_001 and make/install, but it seems the ABI is changed to  3.4.0-0.
Thus I found the file ~/uhd/host/include/uhd/version.hpp, and go through the git log to indicate that the ABI is changed 
with one commit. And then I git checkout to that commit version and make/install again.  The problem solved.

However, can anyone told me what the ABI is used for? And how can I ensure every time the GNURadio is comaptible with 
the installed UHD? Is it corret for what I did for this mismatch problem, or any other way?

I searched archive but did not find related errors ever posted.
